IMPROVEMENT IN CORN-llll'lJ'SKERS.

The Schedule referred to in these Letters Patent and making part of the same.

When 'the strain is not regarded, the section mayl To whom. -it 'ina-y concern Be it known that I, L. AtGLs'ros Asrnvwum., of the city and county of Albany and State of New York, have invented cert-aiu new and useful Improvements inl Corn-Huskers; and I declare the following specification, with the drawings forming a part thereot, to be a full and complete description of my invention.

- Figure 1 represents a perspective view' of the machine, lwith a portion of the top and side broken away. v

VFigure 2 represents a section oi' the' bushing-rolls and cutters.

Figure 3 represents a section ot' t-he gear-vvlieels used upon the rolls.

Similar letters denote similar parts ot' the' apparatus.

A A A is the frameofthe machine.

'.L is thctop or table.

l? is the' band-wheel onwlllie shai't upon which is the picker-roller l), having its surface groovcd aligular. v

Above this, and in combination witlrit, is the plain roller E.

lhese serve to pick oi' remove the ears of corn from 'th stalks. I

Upon the sume, with the ily-wheel is the gearwheel H, connecting with the pinion H, which gives motion to the husking-rolls R R, by means of bevelgears situated underneath the picker-roller D, not shown in the drawing.

The bushing-rolls lt R- are placed on an incline from the picker-roller, as in most machines.

l B are boxes in which the rolls resolve.

G is the incline upon which the ears are conducted to the rolls.

Beneath this is A.nother pair of boxes which supports the upper ends ot' the rolls, also a pair of double gears which connects the rolls, not shown, owing toV their small size, but may bc seen in tig. 3.

L L, S S, are the sides. r

1 l are beveled "des to insure the keeping of the ears lengthwise with the rolls.

Fig. 2 is a section of the rolls lt' 1t, and the cutters M M for the purpose ot' keeping the rolls free from husks.

The method of husk" g corn by means of rolls, as well as picking it from the stalks, is no new thing.

lubber rolls of various construction have been used, also rubber and iron combined; but they lack durability.

lnou rolls provided with teeth upon the surface have been used, but they shell the corn.

llain iron rollsiiil to remove the husks.

lt will he seen that the rolls R R are neither smooth nor provided with teeth upon the surface,

,but are made with sections lr ar turned occent-rically with reference to the rolls, as well as quai-tering, in order that the strain may be equalized.

made to come opposite each other,

extend the entire length of the rolls ou one side.

These sections are provided with teeth I l?.

The points ot' which do not extend above the main surface of the rolls, whicharc certain to catch the husks and not shell the corn.

The sections in the respective pairs of rolls are iu order that the husks loosened by the teeth may beremoved by the smooth surfaces coming in contact, and not shell the corn.

v The rolls may he made with' spaces and teeth in but one, but the work will not be as rapid.

Husking rolls provided with teeth are liable to become wound around with the husks, and cannot .be removed by means of Scrapers; 'it is, therefore, necessary to use cutters, as seen in fi lhe gear-wheels used upon the husking rolls of all machines must necessarily be small, consequently are subject to a heavy strain, and are liable to break qulte etten. To avoid this the gears L L, iig. 3, are used, which are double, and may be tripled or quadrupled,

vhaving teeth opposite the spaces in each, which gives a constant bearing upon the pitch line, and insures a stronger wheel from the fact of there being double the number of teeth. Although this is not new in itself, the improvement consists in the application to bushing-rolls. 1

The operation of the machine is thus:

The power being applied to the wheel F, gives ino tion to the picker-roller D,

wheel and p inion H, motion is communicated to the rolls R R, all in the direction indicated by the darts.

The stalks then being placed upon the table T, are fed, butts first,betwcen 1) and E,v where they are carried along, and the ears pinched off, dropping them upon the rolls R- R, where the husks are removed, and the ears delivered at B B.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The' husking rolls it R, having the depressed p0rtions r 1 provided withteeth P l, constructed and arranged substantially as shown and for the purposes herein set forth.

2. The combination of t-he bushing. rolls R R, when constructed as described, with the gears L L, when said parts are arranged together: in the manner and for the purpose set forth.

L The combination oi' the knives )I M, with the depressed portions r r of the rolls R 1{,:1nd the teeth l l, when said parts are constructed and arranged to operate in the manner and for the purpose herein set forth.
